The FluentAuth – The Ultimate Authorization & Security Plugin for WordPress contains a stored XSS vulnerability in the fluent_auth_reset_password shortcode due to improper neutralization of user-supplied input. This allows authenticated users with contributor or higher privileges to inject arbitrary scripts into pages, which execute upon page access by other users. The vulnerability affects all versions up to and including 2.0.3. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and partial impact on confidentiality and integrity without availability impact.

An attacker with contributor-level or higher privileges can exploit this vulnerability to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to partial confidentiality and integrity compromise, such as stealing session tokens or performing unauthorized actions on behalf of other users. There is no impact on availability. The vulnerability does not appear to be exploited in the wild as of the published date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the fluent_auth_reset_password shortcode. Monitor vendor channels for updates and apply patches promptly once released.
